According to Chapter 26, what is the specific role of the Guru in helping a disciple achieve true knowledge?

In Chapter 26, the Guru is presented as the sole authority capable of dispelling illusion and granting enlightenment. The text emphasizes that in the world, only the Guru can bestow the knowledge of Truth upon a disciple. The author prays to Sadguru Sai Baba to make his intellect turn inward and to instill unshakeable faith in the Guru's words and the Vedanta. It is stated that without personal experience, spiritual discourse is meaningless. Therefore, the devotee implores Baba to use His power to grant a direct, personal experience of this knowledge, as true awakening only arrives through the Guru's word.
